I want to move my InDesign CS5.5 from my XP computer to my Windows 7 Computer. When I run the installer it fails and says: "Installer failed to initialise. Please download Adobe Support Advisor to detect the problem."

My installer is a couple of years old so I downloaded it again incase it was corrupted but I get the same error message I have downloaded the cleaner tool but don't want to remove my other application Dreamweaver CS5

You really should run the cleaner tool. It may not remove Dreamweaver, but most likely it will. Are you logged in as administrator? If this is a 64 bit version of Win7, make sure you are pointing the installer to Program Files (x86)?

Unfortunately I am not get that far. I run the executable which opens a small window which says it is initialising the installation, the percentage bar increases to the right and then after a minute or so as it gets closer to 100% I get the error message. I am assuming that the option as to where to install would come after it has done its initialising.
